摘      要：AIM:To evaluate the effectiveness of a short-type single-balloon-enteroscope(SBE) for endoscopic retrograde cholangiopancreatography(ERCP) in patients with a reconstructed ***:Short-type SBE was developed to perform ERCP in postoperative patients with a reconstructed ***-type SBE is a direct-viewing endoscope with the following specifications:working length,1520 mm;total length,1840 mm;channel diameter,3.2 *** addition,short-type SBE has a water-jet *** study group comprised 22 patients who underwent 31 sessions of short-type SBE-assisted ERCP from June 2011 through May *** was performed by Billroth-Ⅱ(B-Ⅱ) gastrectomy in 6 patients(8 sessions),Roux-en-Y(R-Y) gastrectomy in 14 patients(21 sessions),and R-Y hepaticojejunostomy in 2 patients(2 sessions).We retrospectively studied the rate of reaching the blind end(papilla of Vater or choledochojejunal anastomosis),mean time required to reach the blind end,diagnostic success rate(defined as the rate of successfully imaging the bile and pancreatic ducts),therapeutic success rate(defined as the rate of successfully completing endoscopic treatment),mean procedure time,and ***:Among the 31 sessions of ERCP,the rate of reaching the blind end was 88% in B-Ⅱ gastrectomy,91% in R-Y gastrectomy,and 100% in R-Y *** mean time required to reach the papilla was 18.3 min in B-Ⅱ gastrectomy,21.1 min in R-Y gastrectomy,and 32.5 min in R-Y *** diagnostic success rates in all patients and those with an intact papilla were respectively 86% and 86% in B-Ⅱ gastrectomy,90% and 87% in R-Y gastrectomy,and 100% in R-Y *** therapeutic success rates in all patients and those with an intact papilla were respectively 100% and 100% in B-Ⅱ gastrectomy,94% and 92% in R-Y gastrectomy,and 100% in R-Y *** the channel diameter was 3.2 mm,stone extraction could be performed with a wire-guided basket in 12
